SNAP-H0O K.

SPECIFICATION forming part of Letters Patent No. 352,669, dated November 16, 1886. Application filed September 13, 1884. Serial No. 143,022. (No model.)

To all whom it may concern:

Be it known that I, EDWARD T. VIYoN, a citizen of the United States, residing in the city and county of New York, in the State of New York, have invented a certain new and useful Improvement in Harness Snaps, of which the following is a specification.

Heretofore the ordinary snap in common use has been made in the form of a metal hook, having a flat steel spring riveted to the inside butt-end oftheho0k,with the other extremity of the spring resting against the inner side of the point of the hook, the purpose of such snap being to hold a ring attached to ananimals harness, and to prevent the ring becoming unfastened or detached from the snap.

Figure 1 is the snap in common use referred to. Fig. 2 is a front view of the same. Fig. 3 is a side view of my improvement. Fig. 4 is a front View of the same. Fig. 5 is a cen tral section of my improved hook, and Fig. 6 is an endwise view of the hook portion.

Similar letters refer to the several parts throughout the several views.

A shows the metal hook, B the steel spring; and O the point of impact of the spring B and hook A, as these several parts appear in the old-style snap.

In the improvement, A is the metal hook. B is a straight, curved, or hooked spring. 0

is the bearing-point of the upper end or point of the spring.

Instead of the moving end.of the spring being received into a depression in the end of the rigid hook, I make an opening or mortise, D, entirely through the hook near the end. The faces of the mortise are inclined, and the mortise is largest at its inner end, andthe point of the spring is bent outwardly to enter into the mortise. By this means the spring is sustained against any lateral strain that might tend to press the spring sidewise and allow the ring to escape, and so long as the spring is not actually broken it will retain the ring until the spring is pressed in bodily to movethe point of the spring out of the mortise in the hook.

I claim as my invention- A solid metal snap-hook having an aperture or mortise through the metal nearthe end of the hook, said aperture being widest at the under surface and beveled, in combination with the spring that is fastened at its broader end to the body of the snap-hook, and its tapering moving end is curved outwardly to pass into the mortise, substantially as set forth.
